As of about 2014 ish it is now ok to use fcc approved am/Ssb CB rigs in the UK.

• For 11 meter (CB) the standard 40 channels will be the exactly same as the "EU" set of frequencies (channels). However the "UK" 11 meter (40 channels) and the U.S.A. 40 11 meter (40channels CB) will not work together at all. This includes any actual Citizen Band radio, excluding Export 10 an 12 meter radios often labeled as "CB'S" which they are not.

• Hope this helps.
